Operating using Telnet
It is not the intention of this guide to detail all of the operations and functionality of
Telnet; however, some basic level of understanding is necessary for operating the DXP
switcher via Telnet.
Connecting to the DXP (Open command)

command. After your computer is
connected to the switcher, you can enter the SIS commands the same as you would if you
were using the RS-232 link.
Connect to the DXP as follows:
1.
At the Telnet prompt, enter

Local echo
Once your computer is connected to the DXP switcher, by default Telnet does not display
your keystrokes on the screen. SIS commands are entered blindly, and only the SIS
responses are displayed on the screen. To command Telnet to show all keystrokes, enter
set
local_echo
at the Telnet prompt before you open the connection to the switcher.

Example:
1*1!In1
Out1
All
,
where
1*1!
is the SIS command and
In1
Out1
All
is the response.
Note that all keystrokes are displayed, even those that should be masked, such as the
password entry. For example, when entering a password with local echo turned on, you
see a display such as
a*d*m*i*n*
, where
admin
is the keyed-in password and
*****
is
the masked response.
Local echo can be turned off by entering
unset
local_echo
at the Telnet prompt. If your
computer is connected to the DXP switcher, and you need to access the Telnet prompt to
turn local echo off, enter the
